Hello,

It takes so much time for me to find this small screen to visualise music. I've found this screen on one of chinese supply sites: https://www.dhgate.com/product/2-4-...yzer/425907224.html#s4-16-1b;searl|0772317129
I would order this one but the screen is a little bit too big. Since it's available to buy on this kind of market sites I assume it's not hard to make.

How could you make the same screen with the same ability to visual analyze music? I need a screen up to about 2 inches. It's very important to have the device as small as possible.

Thank everyone in advance.

 

Buy that one.

It's actually a rather challenging project to build such a thing- not recommended unless you are experienced with
programming and digital signal processing stuff.

 

An OLED screen makes a lot of sense, maybe 2 color, many variations
on market (and a whole lot cheaper display) -
